My Computer Wont Start Up

please help!
my computer wont start up.
i dont know why it wont even beep when pressing the power up button.
it just stops right after u switch it on.
i would be grateful if anyone could help

Stupid idea maybe, but try to unplug your main powercable (for 10 seconds) on the back.
Plug it back and start again!

There could be a lot explanations for that... but try this first!

Don't you get any message? No bliebs? Nothing?

still nothing
absolutely nothing

Ooooo....this one hurts. :( You could have done a whole bunch of stuff to your comp. Can you provide any more details as to when it stopped turning on? Where there any bright flashes/smoke/John Philip Sousa music? :blink:

Looks bad man... :(

But really nothing? no spinning fans?

Don't you even hear the Powersupply running?

Maybe some loose cables? Check them all!
Could be very simple...
Monitor cable still fully connected?

Just run through the basic normal simple solutions first.... if nothing helps, than i think your Powersupply is dead!
I'ts replaceble...

Good luck man! (I feel sorry for you! :( )

right heres what happens when i stitch commi on:
all the fans and hard drive and stuff powers up
but then nothing.
blank!

and heres what i think i might of done wrong:
i tried installing a 256MB sdram.
after that it didnt work.

Take out the new ram and try again.

If that doesn't work remove the ram you have and clean its contacts and reinsert.

Did you move anything else? Check those connections and wires.

sound nasty had the same thing on a friends now the bad news

spoke to memory company no power on test no beeps they said maybe the motherboard is dead or the chipset like i checked on cables memory nothing pc has gone back as by luck still under 1 year old hope yours is or just a cable needs a push good luck.

umm sounds like my cuz computer... lol....

like someone said try power supply.... try fan.... try monitor..... suggestions... lol..... mine wouldnt open because my power supply / fan burned to ashes... sigh*... i was thinkin fire....! lol lucky the steel frame prevently anything serious

Did you install a new RAM next to the older one?

Just remove the new one first to check if the older one(s) still works.. (Hope is does!)
If they do... replace it again...

If it doesn't work again.., try the new Ram first, and start again.. (Maybe it' s broke you know?)
If it works with the new Ram, replace your older Ram's next to it... see what happens...

Puzzle a bit with this, but be carefull what you touch... alway's be carefull!
A flatcable disconnects very easy.. mostley just 1 side but that's enough!

I alway's run a check through all my cables before i start it again after a update.. Just press them firmly!

Good Luck!

get another hard drive and plug it in... always good to c if your hard drive is dead... but then again it should boot even if it has no hard drive... lol... weird... check cables? ... did you get pissed at your com n kick it... lol... ::cough:: my cousin did that and the com doesnt work now... but im guessin it is his monitor...

how can it be his monitor if he kicked it?

the cable to his monitor is connected to the back..... :P maybe it got loose... n last of all... did you check if your power cable is connected in... i mean those nice plugs w/ 2 little heads... :P.... lolol ... wait did someone shut your electricity... :P

thanks for all the replies everyone.
ill try what youve said and ill get back to you.
i might even try taking the motherboard and all cables off and then put them all back again.
thanks again. ;)
